A.The input power supply is three-phase 380V50HZ. The voltage waveform is sinusoidal, and the amplitude fluctuation is not greater than+5~- 10%. The frequency fluctuation shall not be greater than 2HZ, and each phase shall be symmetrical. There are no higher harmonics in the power grid that are sufficient to damage the frequency converter. B. Temperature: 0~40 ℃ C.Humidity: The relative humidity shall not exceed 85% (20 ℃±5 ℃),D. Altitude: less than 1000 meters E. No severe vibration and impact
LZ600 wire drawing machine
1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.
1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.
1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.
1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.
1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.
1. 6 Before starting the machine, check whether the safety device is normal.
1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.
1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.
1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.
The second Delivery inspection
2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.
2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.
2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use.

China's LED lighting industry has achieved rapid development in recent years, but its expansion has been slow in the consumption of ordinary households. In this regard, China's Ministry of Industry and Information Technology officials said that LED lighting is difficult to popularize the public mainly because of price and other reasons, LED lighting products in the next three to five years. The price may fall to a level acceptable to the public. Ding Wenwu, Director of the Department of Electronic Information of the Ministry of Industry and Information Technology, said today (10) at the Global Efficient Lighting Forum hosted by the United Nations Environment Program that the LED market in China is growing in size and development. Used in various occasions, the future is the biggest development focus in indoor and home lighting. Only the people can use it to show that it is a success. Ding Wenwu said that the current obstacles to the entry of LED lighting products into household consumption are first of all cost issues, followed by quality issues and safety issues, and with the advancement of technology and quality, the price of LED lighting products is expected to be three or five years later. At a level that is acceptable to the public, there are actually many products and energy-saving lamps that are priced at the same price. Ding Wenwu said that China is the world's largest lighting producer, consumer and exporter. In 2013, China's lighting output value has reached nearly 80 billion US dollars, and exports reached 33 billion US dollars. However, most of the exported products are traditional products, so promoting the transformation of China's lighting industry is an inevitable choice, and the best choice is LED, which is also the most efficient energy-saving and consumption-reducing product. According to the data of the Ministry of Industry and Information Technology, the scale of China's LED industry has reached RMB 260 billion in 2013, exceeding US$ 42 billion. It is expected to continue to maintain growth of 20-30 this year and next. Ding Wenwu said, but it must be greatly improved in terms of product quality and safety.
